Abstract: A load driving device includes a driving switching element, an interrupting part, a short-circuiting switching element, and a protecting element. The driving switching element drives a load by controlling energization to the load. The interrupting part is disposed on an energizing path to the load. The interrupting part is not melted by a driving current to the load and is melted by an interrupting current larger than the driving current so as to interrupt energization to the load. The short-circuiting switching element is connected in parallel with the load and applies the interrupting current to the interrupting part. The protecting element protects the short-circuiting switching element.

Abstract: A printed board includes an insulated base, a wiring pattern, and an inspection interrupting portion. The wiring pattern is disposed on a first surface of the insulated base, and includes a wiring portion, a land, and an interrupting portion disposed between the wiring portion and the land. The inspection interrupting portion is made of a same material with the interrupting portion and has a same pattern with the interrupting portion. In order to assure an interrupting performance of the interrupting portion, the inspection interrupting portion is inspected instead of the interrupting portion by applying an inspection current to the inspection interrupting portion.

Abstract: An electronic control device includes a substrate, a plurality of component-mounted wires, a plurality of electronic components, a common wire, an interrupt wire and a protective layer. The component-mounted wires and the common wire are disposed on the substrate. The electronic components are mounted on the respective component-mounted wires and are coupled with the common wire. The interrupt wire is coupled between one component-mounted wire and the common wire, and is configured to melt in accordance with heat generated by an overcurrent to interrupt a coupling between the component-mounted wire and the common wire. The protective layer covers a surface of the substrate including the interrupt wire and defines an opening portion so that at least a portion of the interrupt wire is exposed.

Abstract: A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a normal terminal and a fuse terminal, each of which extends from lands formed in a printed board so as to hold the main body at a position above and separated from a board surface of the printed board. The fuse terminal has multiple leg portions divided by slits. A first leg portion forms an electrical path portion having a cut-off portion, a width of which is smaller than that of other portions of the electrical path portion. A second leg portion has a first supporting leg and a second supporting leg, which are arranged at both sides of the first leg portion. Each of the supporting legs is connected to each of dummy lands formed in the printed board.

Abstract: A switching power supply converts an input voltage to a predetermined output voltage by controlling a switching device. The switching power supply includes a controller and a current detector. The controller controls the switching device. The current detector detects electric current flowing through the switching device. The controller starts a forced-OFF action to forcedly turn OFF the switching device when the current detected by the current detector exceeds a predetermined threshold and then ends the forced-OFF action at a start of a predetermined switching period.
